These are the words of the wisest, smartest, and most beautiful person in the world: My Wife. Passes the wife test, passes my test.

I was looking for more support something not too hard and not too soft and I settled for the plush and it’s perfect!

I love the Serta Knox firm mattress! Even though it is firm, it is comfortable and I can sleep without any issues.

Perfect Sleeper. We're able to sleep at night. Very satisfied with with our back problems. Problem satisfied, very firm comfortable.❤️👌

This mattress is firm and supportive exact comfort for me with a touch of softness like a pillow top. I just love it.

Our new Serta mattress and box springs are very comfortable and supportive (for my bad back). This mattress is very well made.
